Abstract: Accurate recognition and effective management of coupling relationships among multidisciplinary design models is fundamental to implementation of Multidisciplinary Design Optimization in complex product developments. In view of the demand of complex product developments, a conceptual model of multidisciplinary coupling relationships is built by adopting the set concept. Subsequently, an object-oriented method is used for parameter recognition and representation; and automatic interconnections among multidisciplinary model solvers (design systems) are created by parsing data files. The parameter mapping approach controls and manages data generation, access, conversion, storage and computation processes at individual parameter granularity, enabling interoperations among heterogeneous multidisciplinary data sources. The approach also enables integration of coupled disciplinary model solvers, and effective coordination of multidisciplinary computation processes. The parameter mapping approach has been applied to aero-system developments, and which significantly improves the efficiency and quality of design.
